Doosan DX140W-5



Complete more tasks with the Doosan® DX140W-5 wheel excavator. Its fast travel speeds allow you to easily travel to nearby job sites. Complete utility repairs, construction tasks, street maintenance as well as many other tasks.

Its modular frame design allows you to easily configure the machine’s undercarriage with a dozer blade or outriggers. Level or backfill material with the dozer blade, or stabilize the machine during digging applications. Control the outriggers individually to level the machine on slopes.

The front axle oscillates and provides an excellent steering angle for maneuverability but can be locked for better digging and lifting performance. The rear axle is fixed. The transmission is mounted directly to the rear axle for protection from obstacles and optimum ground clearance.

The Electronic Power Optimizing System (EPOS) deliver optimum power and fuel efficiency. The design optimizes combustion and torque for faster cycles and maximum results. Four work modes, auto-idle and machine diagnostics help you manage your fuel costs. Smart Power Control (SPC), when enabled, improves machine efficiency while maintaining productivity and reducing fuel consumption when you operate in Work Mode.

A standard 7-in. color LCD display provides helpful maintenance history and monitoring information. It also displays video from the rear-view camera, which is uniquely placed to give you better visibility to blind spots. A hybrid screen mode enables you to see machine information and the camera at the same time.

An advanced disc brake system works directly on the hub instead of the drive shaft to avoid planetary gear backlash. This eliminates the rocking effect associated with working free on wheels. The driveline allows more comfort when traveling thanks to increased smoothness and improved hydraulic retarding and gear shifting.

A spacious cab means better visibility and more productivity. High-performance air conditioning, extra storage and an optional air suspension seat give you better comfort, while ergonomically-designed joysticks provide maximum operating comfort. Use the floor foot petal to control two-way auxiliary functions. During long work days, you’ll appreciate the reclining, height- and weight-adjustable standard suspension seat with a headrest and adjustable armrest. An emergency engine shutoff is conveniently placed at the seat base.

Enjoy reduced maintenance costs and extended machine life with the durable chassis, strengthened boom and arm assembly, and extended greasing intervals. Easily access the oil filter, air cleaner, fuel filter, radiators and other engine components. The centralized boom and arm grease points are grouped for easy maintenance. Monitor your Doosan heavy equipment and manage maintenance to reduce operating costs with Doosan Connect Telematics.

To comply with Tier 4 emissions standards, the DX140W-5 incorporates a high-pressure common-rail (HPCR) fuel delivery system as well as cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst (DOC) and selective catalyst reduction (SCR).
